Reported rates of anxiety, depression, and lack of attention in adolescents have been on the rise for the past decade. The Centers for Disease Control reported that one in five high school students meets the criteria for a mental health disorder. School leaders are trying to address the growing challenge by providing students with tools they can use to manage challenging emotions as they arise. Mindfulness is one technique that may help adolescents address these challenges. This qualitative study addressed the perceptions of teachers and administrators toward the implementation of a mindfulness curriculum in a high school. Although many mindfulness programs exist, this study explored the "Learning to BREATHE" mindfulness curriculum, which is a research-based curriculum for high school students. The sample included eight teachers and four administrators from a midsized public suburban high school district in the Midwest. The study utilized semistructured interviews and a focus group to elicit teachers' and administrators' perceptions and thoughts. Four themes emerged from the data including the belief that a mindfulness curriculum could help students manage stress and anxiety and improve students' focus and attention. Another theme was that a mindfulness program necessitates buy-in from both teachers and administrators, time for training, connection to research, ongoing support, and a research-based curriculum. These results are consistent with those of other researchers who studied the effects of mindfulness on adults. Additional research is needed because this study only included one district. The results suggest that if school educators devote time and resources to a research-based mindfulness curriculum, there are opportunities to connect the curriculum to social-emotional state standards that would allow for implementing a mindfulness program that can benefit students' social-emotional and academic well-being.
